Problems solved by technology

It is well known that the sliding performance of the image bearing member is greatly deteriorated due to the attached discharge product.
However, for a conventional image forming apparatus that employs an image bearing member having a rough surface or an image bearing member of which an amount of scraping is reduced, a balance between the amount of the attached discharge product and the scraping function performed by the friction member cannot be kept, and the discharge product will remain on the surface of the image bearing member.
When the printing is restarted while discharge product remains on the surface of the image bearing member, the sliding performance of the cleaning blade across the image bearing memb

Abstract

An image forming apparatus includes a charging unit for charging an image bearing member, an image forming unit for forming a toner image on the image bearing member that has been charged, and a cleaning unit for contacting the image bearing member to clean the surface of the image bearing member. In the apparatus, a ratio of a period wherein the image bearing member is moved without being charged to a period wherein the image bearing member is moved while being charged, is controlled to be a predetermined value or greater.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image forming apparatus, and in particular it is preferable applied to an image forming apparatus, such as an electrophotographic apparatus in which an image bearing member is repetitively used and a cleaning device is equipped for bringing a cleaning member into contact with an image bearing member and collecting a residual material, such as residual transfer toner, from the surface of the image bearing member.[0003]2. Related Background Art[0004]Various types of electrophotographic copiers have been in practical use. These copiers form an electrostatic latent image on the surface of an image bearing member, such as a photoconductive photosensitive member; clean the surface of the image bearing after the development process and the transfer process have been completed; and thereafter perform the latent image forming process again.[0005]A system for bringing a flexible conductive roll...
